The bout is slated for the preliminary card of UFC 139, which takes place Nov. 19 at HP Pavilion in San Jose, Calif.

The main card, including a light-heavyweight headliner between former champ Mauricio “Shogun” Rua and recent Strikeforce titleholder Dan Henderson, airs on pay-per-view.

Bailey vs. Castillo is the 12th addition to the card.

Bailey, a cast member on “The Ultimate Fighter 13,” halted a two-fight skid and got his first official UFC victory with a unanimous-decision win over Ryan McGillivray at the show’s live finale. But in his second fight for the organization, he dropped from welterweight to lightweight and recently suffered a unanimous-decision loss to Evan Dunham. The Indianapolis-based fighter is now 1-3 over his past four fights.

Castillo, a longtime WEC fighter who went 5-3 in the organization, made a successful UFC debut with a unanimous-decision victory over Joe Stevenson at UFC on Versus 3. It marked his third straight victory, though the Team Alpha Male fighter recently suffered a UFC on Versus 5 decision loss to Jacob Volkmann.

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
